Justin Ruggles	4795362660	golomb: check remaining bits during unary decoding in get_ur_golomb_jpegls() Fixes infinite loop in FLAC decoding in case of a truncated bitstream due to the safe bitstream reader returning 0's at the end. Fixes Bug 310. CC:libav-stable@libav.org	13 years ago
Michael Niedermayer	bcbb30e2a0	libmp3lame: add missing layout terminator Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Mans Rullgard	30f515091c	h264: allow cropping to AVCodecContext.width/height Override the frame size from the SPS with AVCodecContext values if the latter specify a size smaller by less than one macroblock. This is required for correct cropping of MOV files from Canon cameras. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Kostya Shishkov	cac4760bf4	iac: generate codec tables as they are supposed to be Unlike its predecessor, Indeo Audio codec generates tables depending on sampling rate. Previously decoder used pre-generated tables for 22050 Hz which obviously doesn't work with other frequencies. Many thanks to Maxim Poliakovsky for providing all needed information for this.	13 years ago
Kostya Shishkov	e1a3fa5d3a	indeo4: handle frame type 1 properly It turns out that this frame type is actually intra and should be used as a reference for interframes too.	13 years ago
Justin Ruggles	d5a7229ba4	Add a float DSP framework to libavutil Move vector_fmul() from DSPContext to AVFloatDSPContext.	13 years ago
Justin Ruggles	98db4e2a4e	PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutil This will allow for easier implementation of Altivec functions in libraries other than libavcodec.	13 years ago
Justin Ruggles	94d2b0d2fd	ARM: Move asm.S from libavcodec to libavutil This will allow for easier implementation of ARM-optimized functions in libraries other than libavcodec.	13 years ago
Mans Rullgard	bc92214e27	vc1dsp: mark put/avg_vc1_mspel_mc() always_inline This ensures that these functions are inlined into the per-position entry points, allowing constant propagation as needed for proper optimisation. 18% faster VC1 decoding on Cortex-A9. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Alex Converse	ecf79c4d3e	vorbis: Validate that the floor 1 X values contain no duplicates. Duplicate values in this vector are explicitly banned by the Vorbis I spec and cause divide-by-zero crashes later on.	13 years ago
Kostya Shishkov	c6061443f7	Indeo Audio decoder	13 years ago
Kostya Shishkov	34271cabac	imc: make IMDCT support stereo output This will be useful for Indeo Audio decoder which is almost the same but supports stereo.	13 years ago
Kostya Shishkov	c45e2da617	imc: move channel-specific data into separate context This will be useful for Indeo Audio decoder which is almost the same but supports stereo.	13 years ago
Kostya Shishkov	b56825c40e	mpc8: fix maximum bands handling In Musepack SV8 codec property tell the maximum nonzero band, but every frame codes maximum band as a limit (i.e. strictly less than given value). Synthesis also expects maximum nonzero band, so there's a need to convert frame maximum band limit value.	13 years ago
Alex Converse	79c8e29a7e	aacdec: Turn PS off when switching to stereo and turn it to implicit when switching to mono.	13 years ago
Kostya Shishkov	96fadfb158	bmv: add stricter checks for invalid decoded length This makes decoder handle random data passed as BMV frame data.	13 years ago
Anton Khirnov	cf3a1948e9	avpacket: fix duplicating side data. Use correct side data size instead of just zeroed field.	13 years ago
Ronald S. Bultje	6163d880c0	vp8: move block coeff arithcoder on stack. This prevents gcc from assuming that contents of it may have changed between calls to vp56_range_get_prob(), thus preventing countless (and unnecessary) movs. Decoding of sintel trailer goes from (avg+SG) 9.796 +/- 0.003 to 9.635 +/- 0.010.	13 years ago
Christian Schmidt	d041dec3cb	pcm-mpeg: improve log message wording We support every defined value for channel layout, bitrate and sample depth. All other values are not unsupported, but reserved. Update comments to say "are used" instead of "are known or exist". Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	13 years ago

Kostya Shishkov	b37d945dd4	mp3: fix start band index for block type 2 in 8kHz audio In hybrid frames long window part ends at 36 samples for most of the cases but at 72 for 8kHz case. For some reason decoder assumed it's 48 or even 36 samples, which caused wrong bitstream decoding for such blocks. l3_25207.mpg from conformance suite demonstrates it the best.	13 years ago
